Prompts that pair well with Grammarly
Four-pass editing checklist applied in sequence
Editing in passes (structure → flow → line → polish) catches issues in the right order. This prompt forces the model through all four explicitly.
Rewrite a canned support reply to sound human
Canned responses get read like canned responses. This prompt keeps the answer's content intact while removing tells.
Re-anchor tone after a hostile customer message
When a customer sends an aggressive or threatening message, your reply sets the emotional trajectory of the entire conversation. This prompt helps you draft a response that acknowledges frustration without matching it or caving unnecessarily.
Write a proactive outage notification for affected customers
Getting ahead of an incident with a clear, honest outage notification reduces inbound ticket volume and builds trust. This prompt structures a message that covers what happened, who is affected, and what comes next—without vague filler.
Decline a customer feature request without losing goodwill
Saying no to a feature request is one of the most common and most mishandled support tasks. A poorly written decline feels dismissive; an over-promised one creates future problems. This prompt helps you draft a reply that is honest, warm, and closes the loop cleanly.
